You have posted your message in the section of this community given over to Nighthawk WiFi Routers. (This is easily done, given Netgear's impenetrable community structure.)

To save you wasting your time, you might get more help, and find earlier questions and answers about your hardware, in the appropriate section for your device. That's probably here:

I will ask the Netgear moderator to move your message.

   Plenty of other insignificant differences might be possible, too.
